WORKING HEAD FOR POWER-PUMPS.

To all whom- '1' t may concern:

lle itkuown that I, lnuar A. luvnns, a

citizen of the United States, residing at Ashland, in the county of Ashland" and State of Ohio, ha ve invented certain new and useful lmproven'ients in Yorking Heads for lower-llunps, of which the following'is a specification, reference being had therein to the a er-onl mnying drawings.

The present invention relates to working heads for power pumps and has for its object the production of a working head for a pump of this character of such a construction that the several parts can be readily moved to permit of access to the interior of the head, whereby the working parts can be rcn'ioved without disconnecting the discharge pipe from the base, without loosening the fasted ings which secure the base'to the platform or other supporting structure and without disconnecting the driving mechanism.

7 \Vith this object in View my invention consists of certain novel features of construction hereinafter descrilmd, and 1nore fully pointed out in the claims.

In the accompanying drawings, Figure l is a side. elevation of a working head enibodying my invention; Fig. 2 is a vertical sectional view of the same; Fig. 3 is a top plan view of the same showing the driving wheels and the gears in section; Fig. 1 is a t'ront elevation of a portion of the working head, showing the cross head in detail; Fig.

5 1s a plan view of the base, with the capreiuoved; Fig. (i is. a sectional detail View of the supporting plate or bushing through the suction pipe; Fig. 7 is a vertical sectional view of a portion ol the base of a modified form of the device; Fig. 8 is a top plan View of the modified form; and Fig. t) is a front elevation of the upper portion of the same.

In these drawings 1 have illustrated the preferred form of my invention, in which the reference numeral 1 indicates the usual basewhich is provided with a flange 2 for securing the same to a platform or supporting. structure. The base is provided on its rear side with a bearing lug 3, in-which is journaled a drivingshaft at, extending beyond theloase at either end thereof and provided at one end with asuitable drivin pulley 5 and an idler 6 and at its other em? with a pinion 7 secured thereon-by a suitable-collar 8 The front or opposite side of thc base Specification of Letters Patent.

which is journaled an operating shaft 10, extending beyond the base at either end thereof and provided at one end w1th a.

gear 11 meshing with the pinion 7, and provided with a Wrist pin 12 on which is mounted the lower end of a connecting rod 13, the upper end of which is secured to one end of the cross head 14:. The op osite end of the operating shaft is provided with a crank arm 15 havinga wrist pin 16, on which is mounted the lower curl of. a connecting rod 17, the up 361 end of which is secured to the correspon ing end of the cross head 14:. The cross head 14: is provided with vertical bearings 18, adapted to receive the guide rods 15) and 'to reciprocate vertically thereon. The guide rods 19 are rigidly secured near their lower ends in the opposite ends of a substantially semicircular supporting frame 20, whiclris pivotally connected at its rear or central part to a suitable bearing lug 21, extending rearwardly from the base 1, by means of a pivot pm 22. Those portions of the guide rods 19 which extend beyond the supporting frame 20 are screw-threaded, as shown at 23, and are adapted to extend through the oblong apertures 2st formed in the lugs or ears on the base 1. The threaded ends "23015 the guide rods 19 are provided beneath the lugs 25 with suitable nuts 26, whereby the supporting frame and guide'rods are rigidly secured in their nornial or vertical position. The cross head l-l' provided with a central enlarged port-ion 27 having a vertical aperture 28 adapted to receive the upper end of the pump rod 29 and provided with suitable means, such as the screw threads 30, to prevent the vertical movement; of said pump rod within the cross head and render the pump rod laterally detachable therefrom. In order that the pump rod may be readily separated from the cross head, the latter is formed in. two parts, as shown, the dividing line extending vertically through the aperture 28 and dlviding the same near its center. The detached ortion 31 of the cross head is of substantiailly the same length as the enlargedportion 27 thereof and is rigidly secured to the cross head proper by means of suitable bolts 32. f

The base 1 isprovided near its upperend with an enlarged portion 33 forming a shoulder 31 in the interior of the base ada- )ted'to su )port the bushing 01. plate whlch is provi ed with a centrt lyarrangedscre'w- 'threaded aperture 36 which is adapted to receive the upper end of the suction pipe 37 and support the same inrits proper position within the base. fits snugly upon the shoulder 34 and is held semrely thereon by suitable means to form a water-tight joint.

This bushing or plate 35 divides the enlarged portion 33 of the base from the remainder thereof andforms a chamber 38 which is provided with an outflct-aperture 3D, to which is connected the discharge, pipe 40. The chamber 38 is closed at its upper end by a cap 41 having a'central aperture 42 to permit of the passage of the pump rod 29. This aperture is preferably screw-threaded to receive the screw-threaded stul'ling box 43, in which the pump rod reciprocates. The inner surface of the ca 41 is provided with a downwardly exten ing sleeve 4st surrounding the aperture 42 and forming a guideway for the pumprod. The sleeve 44. preferably terminates a short distance above the bushing and is provided with a series of outwardly projecting arms 45 of such length that they will engage the upper surface of the bushing or plate and retain the same firmly in posi tion, when the cap 41 is in position onthe upper portion of the base '1. The cap 41 is provided with a suitable packing 46 and is secured to the base 1 by means of suitable bolts 4C7 extending through the cap and through the flange 48, surrounding the upper edge of the base 1 and provided with nuts 50 on one end thereof. The bushing or plate' :35 is provided with links or staples 49, rigidly secured thereto and extending upward to afford means for attaching the same to a cable or other hoisting means for removing the bushing and suction pipe from the well.

lVith the parts in their normal csition, shown in full lines in Fig. 1, w ien it is desired to gain access to thefinterior of the head to remove the working parts, or for any other purpose, the boits-32 are loosened and the detachable portion 31 of the cross head 14 is removed, thereby allowing the screw-threaded end of the pump rod 29 to be readily removed from the aperture 28 in the cross head. The nuts 26 are then re moved from the screw-threaded ends 23 of the guide rods 19 and the connecting mech-v anism and its supporting frame 20-can then. be tilted backward by swin ing the same.

about the pivot pin 22, thee ongated ap er turcs 24: allowing the lower ends of the guide rods 19 to free themselves from the lu s 25 .of the base 1 as the frame is tilted. hen

the connecting mechanism and its support,- ing frame swin back into the position shown in dotted lines in Fig. 1, all obstructions are'removed from above the base, and,

by loosening the bolts .47 and removing the (up 4!, free access can be had to the intorimof the working head and the working The bushing or plate 35" of the drawings; In these figures the refer' ence numeral 51 indicates the. upper end of the base, the diameter of the hollow interior of the same being substantially uniform throughout its length. The base is prefer ably provided near its upper end with an enlarged portinn52 inwhich is provided a passage 53 extending from the upper of the base to a point below the top thereof. The 11 per end of the hollow base is closed ture 55 which is surrounded by a screwthreaded boss 56 which receives the upper end of thesuction pipe 57 and supports the same centrally of the, hollow base. plate is of such a diameter that it extends beyond the edge of the base and is secured thereto by suitable screws or bolts 58. The plate 54 is also provided with a suitable aperture 59 registering with the passageway 53311 the Wall of the base 51. A hollow cap 60, preferably of the form known as ducknest caps, incloses the entire upper end of thebase 51' and is provided with a flange port-ion 61 which is secured to the flange 62 of thebase 51 by means of suitable bolts Theinternal diameter of the cap is sulficient to allow it to fit over the edge of the plate 54, and a suitable packing is interposed etween the flange 62 of the base 51 and both the plate -54 and the flange 61 of the cap. lThe cap 60 is also provided with a central aperture in which is mounted a stuffing 190x64 which forms a bearing for the pump rod 65 which extends through the cap and into the suction pipe 57, as shown. The

base is provided with apertured ears 6t; on wluchare rlgidly mounted guide rods 67,

preferably by screwing the lower ends there- This by a p ate 54 provided with a central aperof into the apertures 66 and providing the same with suitable jam-nuts 68 on the'projecting ends thereof. The rods 6? are adapted to engage the vertical bearings 6E) inthe' cross head 70 and form uides for said cross head. -The cross head $0 is operated from the drivng mechanism by means of the C011}- necting arms 71 and serves to connect said driving mechanism with the Dump rod 65, which is secured in a centra aperture 72 formed in the cross head. 1 The cross head 70 preferably consists of two parts, the line of division extending vertically through the bearing apertures 62) and the central aperture 72 and extending longitudinally of the 7 part of the bases,

cross head to the extreme outer edges of the bearing apertures (3.); and thence extends forward through the outer wall of the cross head, as shown at 73. The detachable portion 74 of-the cross head is rigidly secured to the eross head proper by means of suitable bolts or by other suitable means. \Vhen it is desired to gain access to the interior of the base 51, the bolts 75 are removed from the cross head and the detachable portion 74 thereof is removed.- The body of the cross head 70 is then moved away from the guide rods (37 and the pump rod 65, thus moving the cross head out of alinement with the hollow base and pernitting the ready removal of the pump rod, suction pipe and their coiiperating parts. This form of base and means for supporting the sucton pipe, as more clearly shown in Fig is not specifically claimed in the presen application as it forms a part of the subject matter of a co-pending application for patent. filed June 12, 1909, Serial Number 501,703. Thus, it will be seen that I have provided for remvoin quickly and easily the connecting means rom a position which would interfere with the withdrawal of the pump rod and the accompanying parts to a position which will leave the course clear to etl'ect such awithdrawal, I have here stated and described two forms of construction for this purpose. ()ther obvious forms may also be adopted without departing from myinvention. It willful-the! be noted that among the parts which accompany the withdrawal of the pump rod is the cap 41 or its equivalent used for closing the upper I wish it 'to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.
